    Bison Rising Megaways: Jackpot King Game Overview

    The bet sizes available in Bison Rising Megaways: Jackpot King range from 10p to £10.

    Betting in this game features up to 117,649 ways to win.

    Cascading Symbols

    In this game, winning symbols cause a chain reaction whereby they are removed from the reels, being replaced by new symbols which drop down from above.

    There are symbol positions above reels 2, 3, 4 and 5 which aid the formation of wins. They are the only positions that can reveal Wild symbols, and they are replaced from the right-hand side.

    Until no more winning symbols are generated, cascades take place.

    Wild Symbol

    The Wild symbol can only be displayed in the positions above reels 2, 3, 4 and 5, and is able to help you complete wins by substituting for other symbols, with the exception of Scatters.

    On each winning combination, you will only be paid for the highest win.

    Mystery Symbol

    The Mystery symbol can land anywhere on the reels, with all Mystery symbols that appear revealing an identical random symbol.

    Scatter symbols cannot be revealed by the Mystery symbol.


    The Scatter symbol can appear in any of the reels, although it cannot land in the positions above reels 2, 3, 4 and 5.

    Scatter wins are awarded in addition to reel wins, and to unlock Free Spins four Scatter symbols must be displayed.

    Triggering Free Spins with greater than four Scatter Symbols triggers extra Free Spins, depending on Free Spins Selection.

    Free Spins Selection

    When Free Spins begins you must decide between for different options:

    - 15 free spins and the Unlimited Win Multiplier starts at x1. Unlocking Free Spins with extra Scatter symbols awards four extra free spins (per additional Scatter symbol).

    - 10 free spins alongside an Unlimited Win Multiplier beginning at x5. Triggering Free Spins with a greater number of Scatter symbols awards two extra free spins (per additional Scatter symbol).

    - Five Free Spins and the Unlimited Win Multiplier which begins at x10. Activating Free Spins with additional Scatter symbols awards another free spin (per additional Scatter symbol).

    - Mystery Choice: The available Free Spins and Multipliers will be shuffled into six panels. You choose one panel from each category. The values displayed in the selected panels will be used to initiate the Free Spins Round.

    Free Spins

    The Unlimited Win Multiplier will increase by 1 after every cascade in the Free Spins feature.

    In this feature, the positions above reels 2, 3, 4 and 5 are able to reveal Free Spins Scatters, therefore granting additional free spins:

    Free Spins Scatters
    Extra Free Spins

    The total bet that was used to trigger Free Spins is used for the entirety of the feature.

    When the feature ends, you will see the total winnings for your spins displayed. Following this, your account is credited with any winnings, before regular play resumes.
